Oil & Gas - Upstream

„Oil and gas are among the world's most important energy suppliers. Although new deposits are still being discovered, already preceded oil fields continue being serviced, the production of this viscous solids-containing raw material is becoming more complex. By using NETZSCH-Drive Heads and the progressing cavity pump-systems, many of these reserves can be explored and used efficiently.“

Success Stories

Around 30 years ago, an energy supplier in Hannover had started to use an underground deposit for gas storage. After a few years, however, it became evident during pumping of the medium that the geological horizon in which it was stored had emitted substantial oil quantities into the gas. More...

Despite all efforts to promote renewable energies, global demand for crude oil and natural gas has continued unabated. Methane from coal seams and highly viscous oil at more than 10,000 mPas are already of commercial interest, but are just as complicated to extract. In the Qinshui Basin in China the extraction is as difficult as the extraction of oil sand mixtures from the Sudanese desert where temperatures up to 50°C can be reached. More

Pumps for the Oil Industry

NETZSCH pumps for the oil industry are characterized by robust and reliable design. Constructions and materials are adapted to the requirements. Together with the customer's requirements are specified in the planning phase and the optimal pump is selected. The use of innovative pump technologies from NETZSCH offers safe and reliable production processes at low life-cycle costs. On this there is a large range of products available from which you can select the appropriate each pump system for on- and offshore, up-, mid- and downstream area.

Optimum UPSTREAM Solutions for Oil Water and Gas Production

Within the Business Unit Pumps & Systems the Business Field Oil & Gas Upstream specializes in the delivery of systems with progressing cavity pumps for the production of crude oil and other highly viscous materials; the pumps above mentioned are used throughout the world. Whether it is a large oilfield operator or a small production company – the experts at NETZSCH give their attention to all projects. At the same time we try to correspond to the increasing technological demands by highly efficient development work. Success in corporate research and development work with universities and operators of our pumps in the field confirms this fact.NETZSCH Progressing Cavity Pumps for Upstream:

Special Pumps & Systems

NETZSCH Insertable Progressing Cavity Pumps

The main feature of Progressing Cavity Pumps (rotor & stator) is their assembly inside the tubing. Thus, the pump is not connected to the production line but assembled inside it.

Applications

Wells with low flow – the cost of the intervention makes the use of a normal pump economically not suitable

Wells with a high frequency of interventions (independent of the flow)

Flow range 1,3 to 491 bpd at 100 rpm

Pressure range 100 to 240 bar

Pump with downhole sensors

Advantages

Minimization of the time of intervention

Minimization of costs of rig

Minimize rig’s costs in workover services, this minimizes production losses

Pump substitution without removing it from the tubing

Pump substitution with flushby equipment

Up to 60 % savings in pump replacement

Does not require removal of downhole sensors and cable

NTU Progressing Cavity Pumps

Produced with steel tube conform with the same internal geometry as the stator (helical). Thus the elastomer has a uniform wall and produces even distribution of the elastomer. The main NTU pump feature is its lower operation and starting torque due to its lower swelling when exposed to temperature variations and chemically aggressive fluids.
